Definitions

  • the invention relates to an endless, belt-shaped tension element for a conveyor with at least one connection point comprising an elastomer, in particular a crosslinked and / or thermoplastic elastomer, at least one reinforcing layer and optionally at least one tensile carrier, wherein arranged at the at least one connection point two ends of the at least one reinforcing layer are, a conveyor with a continuous, endless, band-shaped tension member and a standing with the tension element operatively connected drive means and a method for producing an endless, band-shaped tension element in which an elastomer a Switzerlandelementprofil is prepared, arranged on this or in this one reinforcing layer and these are then connected by temperature treatment and their use.
  • Ribbon-shaped tension elements with very different cross-sectional shapes are made of numerous applications, such as e.g. Conveyor belts for objects or people, handrails for escalators or moving walks or the like., Known. Typical applications are e.g. also belts or belts, these being used in many cases for the transmission of drive power or material transport.
  • Conveyor belts are known to consist of a circulating endless belt, which is partly supported by deflection rollers, which are arranged at the two opposite end portions of the belt.
  • the endless conveyor belts are usually made of a composite material between rubber and / or plastic with tissues and have to reinforce fabric, knitted or steel inserts, and depending on the application area, one or more tensile carriers to increase the breaking strength in the direction of the loads occurring.
  • the generation of the endless belt results in at least one connection point of the two opposite ends of the belt.
  • Handrails for escalators, moving walks or similar applications are used as security elements for passenger transport.
  • the handrail must allow the passenger a secure grip and be able to cope with the dynamic stresses or the environmental influences during operation without being damaged.
  • the touchable by the passenger handrail surface is usually made of an elastomer mixture.
  • the handrail cover also protects all underlying components against various environmental influences and must therefore be resistant to them.
  • reinforcing inserts such as fabric, Gewebecorde, short fiber reinforced mixtures, etc. are used. It is expected that the handrail will last as long as possible.
  • the handrail contains in its cross section for receiving longitudinal forces so-called tension members, which must have a defined minimum tensile strength in the joint area.
  • the so-called sliding layer forms the contact surface of the handrail to the handrail guide or the handrail drive system.
  • connection points of two ends of an endless belt are known from the prior art.
  • US Pat. No. 6,086,806 describes the connection of two ends of an endless belt by means of a finger connection principle.
  • US 5,083,985 the finger connection technique is described.
  • EP 0 185 006 A1 describes the finger connection in combination with an intermediate plate covering the finger joint.
  • a connection of two ends of an endless belt by means of an intermediate piece or cover piece is known for example from US 4,618,382.
  • the ends of the endless belt and the ends of the intermediate piece are joined together.
  • recesses may be arranged in a region in which tension members are inserted.
  • EP 0 273 479 A1 also describes the use of an intermediate piece between two ends of an endless belt, wherein the intermediate piece abuts the ends of the belt and forms an angle of 45 °.
  • a sandpaper is known, which can also be made endless by the ends to be joined together via a hot melt adhesive.
  • a method is described in US Pat. No. 3,783,063, in which the connection points of the belt are covered by longitudinally or transversely arranged intermediate pieces.
  • the object of the invention is to extend the life of band-shaped tension elements.
  • a subtask of the invention is further, the probability of failure during operation of the tension member to minimize due to breaks at the joints of the tissue.
  • the object of the invention is independently by an initially mentioned endless belt-shaped tension member for a conveyor, wherein at the junction between the two ends of an insert at an angle ⁇ with respect to the Werselementlijnserstreckung is arranged, wherein the ends of the at least one reinforcing layer overlapping with the Insert are arranged by an initially mentioned conveyor, by a method for producing an endless, band-shaped tension element, wherein for forming the endless belt at the junction between the two ends of the reinforcing layer, an insert is inserted at an angle ⁇ with respect to the Buchelementlijnserstreckung and wherein the ends of the at least one reinforcing ply are overlapped and connected to the insert and the use thereof.
  • the advantage of this is that the life of the tension element is considerably extended, because the joints withstand higher mechanical stresses and thus high reliability can be guaranteed. Furthermore, it proves to be advantageous that both high flexibility and dimensional stability are ensured in end-specified tolerance fields of the tension element.
  • the angle ⁇ is selected from a range with a lower limit of 25 °, preferably 30 °, in particular 35 ° and an upper limit of 75 °, preferably 70 °, in particular 65 °, in particular 45 ° , whereby the breaking strength of the tension element increases in view of the loads occurring.
  • the width of the insert is selected from a range with a lower limit of 3 cm, preferably 5 cm, in particular 10 cm and an upper limit of endless preferably 2 m, in particular 50 cm, in particular 15 cm, whereby over the entire length of the tension element a uniform thickness of Werners is achieved and it results in a regular surface, which improves the touch of the tension element, in particular the handrail.
  • the width of the overlap is selected from a range with a lower limit of 3 mm, preferably 5 mm, in particular 8 mm and an upper limit of 1 m, preferably 50 cm, in particular 10 cm. in particular 12 mm, whereby only one, in relation to the entire length of the tension element, short length a multilayer relative to the insert and the ends of the reinforcing element arrangement in the tension element is formed, thereby causing a small increase in the height of the tension element.
  • the overlap region lies between the fabric layer and the elastomer, in particular on the side not visible in the installation position of the tension element, but preferably on the side facing a drive device, whereby the breaking strength and thus life of the tension element can be additionally increased ,
  • the reinforcing layer may be at least partially a sliding layer or a stiffening layer, whereby on the one hand an improved locomotion of the tension element is given on a drive means or the deformability of the tension element is kept within limits and thus the dimensional stability is ensured. Furthermore, it proves to be advantageous that the sliding friction with respect to the guide means is not so high and yet the static friction is sufficient for a drive device by the arrangement of the sliding layer.
  • the reinforcing layer is at least partially formed by a woven and / or knitted fabric, whereby the high mechanical stresses can be compensated or high loads is maintained and thus the tensile strength of the tension element is increased and still the flexibility of the tension element is not restricted.
  • the sliding layer is at least partially made of a synthetic fiber fabric, e.g. Polyamide, polyester, etc. and / or natural fibers, e.g. Cotton, or mixtures formed therefrom, whereby both the one hand, the sliding friction against the guide device is not so high and on the other hand, the static friction for a drive device is sufficiently large.
  • a synthetic fiber fabric e.g. Polyamide, polyester, etc.
  • natural fibers e.g. Cotton
  • the reinforcing layer between the two ends is formed by a continuous fabric web, whereby the number of joints can be kept as low as possible, thereby minimizing the potential breakages.
